NUT-VISE.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed. July 12, 1917. Serial No. 180,116.

To all whom it may concern:

Be it known that I, Pnonn PEDERSEN, a citizen of the United States,residing at Port Oxford, in the county of Curry and State of Oregon,have invented certain new and useful Improvements in Nut-Vises, of whichthe following is a specification.

This invention relates to improvements in nut vises and its prime objectis to provide a device of this class that is simple in construction andcheap to manufacture and that is durable and efficient in operation.\Vith the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed, pointed out in the appended claim and illustrated in theaccompanying drawing which forms a part of this specification and inwhich Figure 1 is a view in side elevation of my improved nut vise.

Fig. 2 is a cross section taken on line L4 of Fig. 1.

Like reference characters denote corresponding parts in both views.

I provide an oblong frame denoted by reference numeral 1, open in thecenter and formed with a shank 2 which may be provided with a handle(not shown). One end of the frame 1 comprises a movable core 4:,separate from the balance of the frame, and which is formed with athreaded opening 4: to receive the screw 5 that is provided with theoperating handle 6. The screw 5 at its inner end carries the head 7provided with the transverse jaw 8 which is disposed in alinement withthe stationary jaw 9 embedded in a grooved portion of the frame 1. Thesaid core 4 is formed with the diametrically opposed sockets 11 and withslots 12 opening into said sockets at right angles thereto. In thesocket 11 I provide lugs 13 that rest upon springs 14 which yieldinglypress said lugs out from the sockets and into grooves 15 formed in theinner lateral edges of the frame 1. Each lug is provided with a handle16 that projects out through the slots 12 and by means of which the lugsmay be retracted to permit adjustment of the core or member at withrelation to the frame 1. When the said handles 16 are pressed towardeach other the core 4, screw 5 and head 7 can be moved instantly to anypoint along the frame 1 and by releasing the handles 16 so that the lugs13 may occupy any pair of grooves 15 said core 1 is locked in positionwith relation to the said frame. The arrangement just described permitsa very quick adjustment of the jaw S with relation to the jaw 9. The nut17 to be removed from the screw or bolt 18 is retained between the jaws8, 9 while the screw or bolt is turned and the nut may be so retainedwhile it is being re-threaded if desired.

WVhat is claimed is In a nut vise, a hollow frame open at one end, afixed jaw carried at the closed end of said frame, the sides of saidframe being formed with a plurality of oppositely disposed grooves, acore movably arranged in said frame and formed with lateral sockets andwith slots opening into said sockets, spring-pressed lugs disposed insaid sockets for yielding engagement with the grooved portions of saidframe whereby said core is supported in adjusted position in said frame,handles for said lugs, extending through said core-slots, whereby saidlugs" may be moved relatively, and a movable jaw operatively carried bysaid core within said frame for cooperation with said fixed jaw.

In testimony that I claim that the foregoing as my own I have heretoaffixed my signature in the presence of two subscribing witnesses.

PEDER PEDERSEN.
